Most of you are already familiar with events at SOTR and it has been a quiet year.
Nikoli Hurdles 4 has just begun and entries are open until 29th October.

Same rules. 8 puzzles to be solved successively. Do mind the answer keys, though.
This set of hurdles feature usual suspects (like LITS and Masyu), and some novelties (you'll have to see for yourself )
The prize this time is Nikoli's Puzzle the Giants 2016 issue.
